SUNNY BOY: On a day like yesterday, when temps hit 90, who cares if your suit gets a little dirty? This businessman lays it all out on the Elevated Acre on Water Street.NY Post: Chad Rachman

It felt like August in April yesterday as the Big Apple baked in record heat.

The mercury soared to 90 degrees in Central Park, burning away the record of 89 set in 1929. That made it a gorgeous 30 degrees warmer than the normal high of 58 degrees.

“After this winter, all I can say is, ‘Hallelujah!’ ” said Kara Mullins, 28, of Brooklyn, who took a day off from her job as a shoe buyer, put on her bikini and headed to the beach at Coney Island with her boyfriend and his 9-year-old son.

Many others flocked to Central Park to bask in the sunshine.

Mike Easling, 50, enjoyed the balmy temps on his day off with a jog.

“They should have declared a holiday for everyone in New York City today,” he said. “Who wants to be at work on a day like this?”

Martha Johns, 29, of Brooklyn, was soaking up the rays. “It doesn’t get much better than this,” she said.
